The suit, filed by Cathriona White's grieving mother, Brigid Sweetman, also claims that Carrey "shamed" his girlfriend before she took her life.

In early 2013, "Carrey hid from Ms. White that he had tested positive for multiple STDs, according to the lawsuit. At the time of his testing he allegedly gave the fake name "Jose Lopez... in order to avoid detection,” the suit alleges.

In a statement, Carrey's attorney reportedly said: "It is understandable that a mother who has lost a daughter will look for someone to blame."

The attorney added, "But in directing her grief and rage at Jim Carrey and joining this … attempt to capitalize on Cathriona's suicide, Mrs. Sweetman is heading down the same dark path as … [her ex-husband] Mark Burton."

The mother's lawsuit comes three weeks after Burton also filed a wrongful death suit against Carrey. His lawyer has called the lawsuit "baseless," "bogus," and a "transparent shakedown."
